Abstract:

Total pressure measurements were obtained in the turbulent boundary layer of a spinning body of revolution in support of the BRL Magnus Research Program. Data were obtained on the boattail section of a slender projectile shape at a Mach number of 3.0 and angles of attack up to 6.3 degrees. This report presents a tabulation of the boundary layer profile characteristics in a format that facilitates comparison with theoretical computations. A description of the experiment and a brief analysis of the data are given.
